your over reacting.OK you re surfaced the carbon face of the pump, but you must give it a chance to match the impeller face . like bedding in brake pads. unless the impeller drive screw is bent and the impeller is wobbling (check)
the expansion tank is a auto regulating thing after filling it has to eject any coolant over what the system can hold when hot (fully expanded)
You didn't mention overheating/
Give the pump a few more miles to wear in you may be OK
Your other recourse is to replace the impeller seal and shaft

Yes tha is part of the weep passage. Look at all the pieces trace the passage from the space between the water & the oil seal to ground.
‘this passage is needed to drain any water or oil away to ground,instead of posabilly contanimating the other .
as you must realize by now the water seal is anything but positive, and som seepage is built in.

Your find. The design of the pump seal has a bit of seepage built in. There is no positive deal just a light spring pressure against a rotating surface,
leave the impeller alone it is self tightening. All you will do is snap the drive shaft .
